The Lowdown
Alright, let’s get real about Kennebunk Beach. I’ve looked through the next 16 days, and I’ll be straight with you – it’s a quiet stretch for the most part. The water temp is sitting around 66°F right now, which is pretty normal for this time of year, so at least you won’t be freezing your toes off if you do paddle out.
The first couple of weeks are a tough watch. We’ve got tiny swell, mostly under 2ft, and the wind is all over the place – cross-onshore, onshore, choppy, or just flat. The combined energy is weak, barely cracking 60-80 (63) for the most part, so there’s just no grunt in the water. Thursday morning the 20th goes glassy, but with only 2ft of SE swell at 8 seconds, it’s not doing much. You’ll be floating more than surfing.
There’s a real gap here – from now all the way through to the end of August, it’s pretty much a write-off. Nothing consistent, nothing with any punch. The break is sheltered and the optimum swell is from ENE, but we’re not seeing that combo line up with any size or energy.
Then, finally, on the morning of Saturday the 29th of August, we get a bit of a pulse. Swell height bumps up to 4ft from the ESE, with a period of 7 seconds, and the combined energy jumps to 182 (moderate). That’s the first real sign of life. The wind is a light cross-off from the ENE, so the surface will be clean. It’s still a short period swell, so expect a bit of a bumpy, close-out feel on the beach, but it’s surfable. The afternoon holds at 3ft from the E with energy at 185 – still clean, still rideable. This is the standout window. It’s not epic, but it’s the best we’ve got.
After that, Sunday the 30th drops back to 3ft, and we’re into another run of small, weak surf. A bit of east swell pops up on the 1st of September, with 2ft from the E at 9 seconds and energy at 175 – clean in the morning, but again, it’s ordinary. The rest of the first week of September is more of the same small stuff.
So here’s the deal: if you’re desperate, aim for the 29th of August morning. It’s the only time the swell, wind, and conditions line up for anything resembling a proper session. The rest of the 16 days? Leave the board at home, or take a longboard and enjoy a paddle. This is a dry spell, and it’s going to stay that way for a while.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
